At some point you may want to let someone have entry to your home for a short time and you trust them enough to let them have the passcode to your garage door. This is, presumably, a safer alternative to giving them a key to a passage door as a key may be lost or duplicated. A few of the folk you may grant access to are:

• House sitter, baby sitter, pet sitter.
• Guest or relative staying with you for a short time.
• Neighbor looking after plants, pets, etc.
• Realtors
• Contractors (painters, electricians, plumbers, etc.)

Although giving someone your regular passcode is a convenience, you should absolutely change the passcode as soon as their tenure in your home is no longer needed. It is not a matter of distrust as much as it is the preservation of your peace of mind knowing that only you control entry to your home.

However

A better way of granting temporary entry to your home is to provide a temporary garage door passcode to the entrant–a passcode to which you can assign an expiration time. You can have the passcode expire within one hour to 255 hours (about ten days). Once it expires it can no longer be used and you can keep and continue to use your regular passcode. If you have a wireless keypad at your garage door, simply open the cover and you will find the instructions for creating a temporary passcode inside the cover; it can be done in less than a minute. I have reproduced the instructions below for your review.
